Amin Rights requested at every clean-up on iMac

CCleaner for Mac
1

Hello, I have a question. I recently purchased CCleaner professional for my iMac running under OS High Sierra. While the clean up runs fine on my iMac, a colleagues iMac running also a valid CCleaner version 1.117.603 every time the Mac password Dialog appears to confirm. I think there is a problem with missing admin rights. But where and how I could set this to allow the access automatically?

Thanks for some advises concerning this

We don't have many Mac users here, I don't use Mac myself.

Is one of you using Safari and the other not? 

And/or are you using different ticks/unticks for cleaning Safari?

This has been an ongoing problem with the Mac operating system, see this 2018 reply from support :
